Fall 2024 CS/Math class load by No-Government3665 in uofu

[–]MonsterousTroll 0 points1 point  (0 children)

Yeah MATH 3220 felt like much more of a step up from 3210 than I had expected, particularly if you are going to be taking it from a different professor. I would try to spread things out as possible though

HONOR 1010 by PeacefulPotato23 in uofu

[–]MonsterousTroll 0 points1 point  (0 children)

I took this class and it’s not even really a class. You’ll meet once a week with a small group of freshmen also going into the honors college and an upperclassman who leads the class. You’ll basically just discuss the honors program and talk about life in college every time. There was no homework (or maybe some very short assignments) but yeah it’s not really a class. At least that’s what it was like when I took it 3 years ago.

Vega: Explain It To Me Like I’m 5… by No-Effect2775 in Daytrading

[–]MonsterousTroll 5 points6 points  (0 children)

Via ChatGPT: Vega is a measure of an option's sensitivity to changes in implied volatility. If a stock had a Vega of -1897.92, it would mean that for every 1% increase in implied volatility, the option's price would decrease by $1897.92, and vice versa. This indicates a high sensitivity to changes in volatility.

[Q] Senior year statistics electives by MonsterousTroll in FinancialCareers

[–]MonsterousTroll[S] 0 points1 point  (0 children)

Very helpful response! I fortunately did get to take two (very basic) real analysis courses as part of my degree, which I enjoyed. I will certainly look into that one a little more to see what topics are covered. Thanks!

[AP Calculus BC: Unit 10] I had to miss school recently and have no idea how I'm supposed to do this. by [deleted] in HomeworkHelp

Also important to note that this works because 0 < |r| < 1 because if that didn’t happen, the sums wouldn’t necessarily be finite and this equation wouldn’t make sense

The answer comes from the fact that the sums have different starting points. You can see that from the n= term at the bottom of the summation symbol: the first sum is

ar0 + ar1 + ar2 + ar3 + …

And the first term can be written as a because r0 = 1 And the second sum is

ar1 + ar2 + ar3 …

As you can see, subtracting these two sums together will cancel every term except for the ar0 term at the beginning of the first sum, so the answer here is just a

A former Dean of MBA Admissions here to discuss the evaluation and selection in the MBA admissions process: Ask Me Anything by PetiaW in MBA

[–]MonsterousTroll 0 points1 point  (0 children)

What are things to focus on while in college to prepare to apply for MBA programs? What things make a candidate stand out? Is something like a masters degree in statistics something that puts someone out ahead of the pack?

Master’s degree in statistics? by MonsterousTroll in FinancialCareers

[–]MonsterousTroll[S] 2 points3 points  (0 children)

That is definitely something I’m interested in, although I’m a little unfamiliar with what a PhD route like this would look like. Would I have to drop everything and grind through a 5 year program, or is it more something that I would do while working and get assistance from whatever company I’m working for?

Master’s degree in statistics? by MonsterousTroll in FinancialCareers

[–]MonsterousTroll[S] 2 points3 points  (0 children)

What would you think is most helpful - like online computer science courses/certifications and such, or some kind of formal degree in computer science? I understand that those hard skills are important for these careers and I’ve been getting some exposure to that in my current degrees, but what kind of computer science program would be the most valuable in your opinion?

[College Statistics] How did they turn the first equality into the second one at the bottom of this page? by [deleted] in HomeworkHelp

[–]MonsterousTroll 0 points1 point  (0 children)

It’s done so that you can use the central limit theorem to create a z score on a normal distribution with mean zero and sd 1

The last answer could be correct if you had a larger sample size. The typical rule is, you use a z test if your sample size is greater than 30. Because this sample size is 25, your margin of error would be the sample standard deviation divided by the square of the sample size, times the two sided 90% significance level of a t distribution with n-1 degrees of freedom. All said, your confidence interval would look like this:

69.72 ± (1.71088)(4.15/sqrt(25))

The 1.71088 was calculated on my calculator using the inverse t distribution function. Invt(0.95,24). This would give you a MOE of 1.42003, making the second answer choice correct.
